My invention relates to impro vements in reflectors and it is one of t he ob;yectg 0f my invntion to provide a. reflector part1cularly adaptable for headlight purpc ses fo r auto- 5 mobiles and the like which w1ll pro]ect the rays of light from the lamp m snch a manner as to cause the greater proporhon of the light to be piojected below a laue which will cause a. dangerous glare of ight in the.

e ves of drivers. of approaching veIncles.

Other objects und advarit21gespf my mvention w'ill appear more fully m the accompanying spebification ang1 cla1 m. 1 For the purpose of dlscloslng my 1 nvention I have illustrated. one embo hment thereof in the accompanyi ng drawingjn. which the figure is a long1tl1dmal sectxon of a headlight embodying my invention.

In the structure. illustrated the reflector 1 is in the form 0f a truncated ellipsoid with the lamp 2 arr&nged at the apex 0f the The lament o f the lamp is adjusted to the focus 8 of the reflector und the cover plate 3 is arranged in the plane of the focus 9 of the reflector. As has hereto'fore been stated, 5 this cover plate m ay take the form of a glass and at the focal point of the reflect0 r the lass is. preferably left clear or provided wibh a lens, while the remaining portion of the glass may be either 0 aque or semitransparent to thus cut 0 or diffuse the sn1all;cone of direct rays emanating from the focus 0f thelamp.

If desired, a deflector 10 may be placed inside the reflector und below the focus so as to deflectall of thc lower' reflected ra s o1'1twardly und downwardly through t e focal opening. While I have illustrated und desc'ribed this deflector as being within the reflector and below, the focal point thereof, it may be if d.esired; be exterior tothe casing and above the -fbcal point und accomplish the same result.

I claim as my invention:

A reflector substantially ellipsoid in shape and truncated at its second focal point, a translucent cover plate fitt i ng said tru ntrated portion und having at the second fot:al point of the reflector a transparent portion und a defiector arranged at said transparent por- 00 tion und constructed to deflect all of the Iower reflected rays outwardlynnd downwardly.

In witness Whereof I, WILLIAM E.

RICHARD, have, hereunto set m'y band at Evansville, Indiana.
